Nightmare Moon rammed Celestia in the side and knocked her off the balcony, then, taking advantage of her initial surprise, Nightmare Moon grabbed Celestia with magic and threw her against the side of the castle. The force behind the throw was so powerful that princess actually went through the wall and sections of it crumbled and fell. Nightmare Moon laughed at the expression of shock Celestia had shown when she had first saw her, and flew through the hole in the wall to finish what she had started. Celestia was lying on her side, one wing broken, horn glowing, trying to heal herself before the attacks continued. Nightmare Moon walked forward and put a hoof on Celestia's glowing horn, ignoring the feeble kicks that the princess launched at her. As she began to put pressure on the horn, threatening to snap it off, Luna came charging down the corridor horn glowing and picked up a piece of the rubble and hurled it at Nightmare Moon, still charging at her, while the two guards ran ahead to attack Nightmare Moon with wing and horn. Nightmare Moon jumped over the projectile and landed in front of the two guards, she allowed one of them to take a stab at her with its horn and sidestepped, then picked up the guard with her magic and threw him at his companion. Luna took flight and skimmed the ground, sweeping Nightmare Moon's legs out from under her. Nightmare Moon tried to regain her balance and failed, flapping her wings wildly while she fell forward. Luna landed in front of Nightmare Moon and bucked her head, while the guards recovered and moved to either side of her.
This was something she had not expected, when she had last seen the Princess of the Night, Luna had been anti-social and weak. Then Nightmare Moon noticed that Luna was speaking to her, "I thought you had been destroyed by the elements of harmony, but it seems i was wrong" Luna took on a almost sad expression "so it seems I will have to finish you myself." Nightmare Moon was scared for the first time in years, how could it all go so wrong? Years of planning wasted because Luna had somehow regained all her confidence and strength in a matter days instead of months like she had expected. Luna broke each of Nightmare Moon's wings with a quick telekinetic pull, and then Luna broke her horn in the same way she had meant to break Celestia's. Then she carried Nightmare Moon over to the hole in the wall and looked at the fall below before letting her drop, but even then, after all that evil pony had done Luna still felt nothing but sadness for her and the fate she had brought upon herself.
Nightmare Moon had been killed to many times, her soul could not take it. So, it shattered. It broke apart into hundreds of fragments, almost all of which immediately died themselves and simply disappeared. There were only three left, one was to small a fragment to form any thought, the other could think but was insane, and one was the largest fragment of the broken soul. The fragment roamed for two years before it finished repairing itself, though its mind had finished most of its repairs the memory was still damaged.
A small black alicorn foal wondered on the edge of the Everfree forest marveling at anything and everything. The little filly heard singing and wondered toward it, she had never heard anything so beautiful before, or at least she did not remember when she last had. The foal tripped and fell face first into a clearing where a yellow pegasus with a pink mane was coordinating the chirping and tweeting of twenty different types of birds, normally this pony was quite shy but she had a weakness for foals. "Oh dear, are you okay?" the pegasus was barely talking above a whisper "Do you need some help? Of course you do, let me take you inside!" without further ado the yellow pony picked up the confused foal and flew to her cottage.
